Functionalized tetraarylphthalimides or diarylphthalimides fused with an acenaphthene moiety have been prepared in one step from 2-bromomaleimide and tetraarylcyclopentadienones (tetracyclones) or 7,9-diaryl-8H-cyclopentacenaphthylene-8-ones (acecyclones). The reaction, involving a cycloaddition-decarbonylation-dehydrobromination sequence, gives high isolated yields and is compatible with the presence of various functional groups.
已通过一步法合成了带有acenaphthene结构的功能化四芳基邻苯二甲酰亚胺或二芳基邻苯二甲酰亚胺。利用2-溴马来酰亚胺与四芳基环戊二烯酮(四环酮)或7,9-二芳基-8H-环戊并苊-8-酮(苊环酮)反应制得。该反应涉及环加成-脱羰基-脱溴化氢序列,具有高纯度产率,且能兼容多种官能团的存在。
